IMPRovl-:D BARREL.

Specification forming part of Letters Patent No. 32,340, dated May 14,1861.

To all whom, t may concern:

Be it known that I, SEERIDAN ROBERTS, of Cleveland, in the County ofCuyahoga and St-ate of Ohio, have invented new and useful Improvementsin Manufacturing Barrels; and I'do hereby declare that the following isa full and complete description of the construction and operation of thesame, reference being had t0 the accompanying drawings, making part ofthis specification, in which- Figure l` is a perspective view of thecylinder part of a barrel Without the hoops, and Fig. 2 is the same Withthe hoops driven upon it.

The nature of my improvement relates to the formation of the cylinderportion of barrels from voluted sheets, cut or removed from the surfaceof solid cylinders, and forming the bulge of the barrel by cutting outor removing gores or Wedge-shaped pieces from each end, but leaving themiddle third entire, so that by bringing these cut ends again intocontact by means of hooping, the cylinder part of the barrel thus formedwill have the desired bulge. The volute or cylinder part of the barrelA'is out with a straight knife from the surface of a log having theproper length for the barrel by means of any suitable lathe or engine. Asuuioient length of such volute is cut off from the sheet as will besufficient for a barrel or Cask, as seen at A in Figs. 1 and 2.

By means of a circular saw or` any other suitable instrument gores orwedge shaped pieces B are sawed or cut out, as shown in Fig. 1, andextending about one-third of the entire length toward the center, thusleaving the middle third entire. These gores or wedgeshaped pieces thatare thus out out may range in width at the outer ends from one-fourth ofl an inch `to half an inch, and number from ten to fifteen foreachbarrel, according to the desired bulge. The gores B,being all saw'ed orout in which case the body of the barrel would be composed of two ormore pieces instead of one piece only. The chines are cut after thehoops are driven on, and the barrel-head made and inserted in the usualmanner.

What I claim as my improvement, and desire to secure by Letters Patent,is

The making of the cylinder part of barrels of a volute piece or pieceshaving gore or wedgeshaped pieces cut from each end, as described, forthe purpose of forming the proper bulge to the body of the barrel, inthe manner herein set forth and described.
